The rise in output power from rare-earth-doped fiber sources over the past decade, via the
use of cladding-pumped fiber architectures, has been dramatic, leading to a range of fiber …

Photonic crystal fibers present a wavelength-scale periodic microstructure running along
their length. Their core and two-dimensional photonic crystal might be based on varied …

Nanotechnology, science, and engineering spearhead the 21st century revolution that is
leading to fundamental breakthroughs in the way materials, devices, and systems are …

Since the advent of quantum mechanics and the clear demonstration of the existence
of'matter waves', physicists have never failed to take advantage of concepts and theoretical …

Optical fibres have for almost three decades been fabricated of solid glass. It was, therefore,
a radical change that took place, when researchers in the late 90's started to fabricate hair …

We report on a 2.3 m long air-clad ytterbium-doped large-modearea photonic crystal fiber
laser generating up to 80 W output power with a slope efficiency of 78%. Single transverse …

The fiber laser, with its humble beginning in the late 1980s, has undergone tremendous
development in the past decade or so, transforming itself from a research curiosity to a major …

An Ytterbium-doped photonic crystal fibre laser is demonstrated with a 100 µm2 core area
and single transverse mode with an output efficiency of 30%. Double-clad PCF laser …

Three centuries after Newton's experiments on the decomposition of white light into its
spectral components and the synthesis of white light from various colors, nonlinear-optical …

▪ Abstract The development of microstructured optical fibers has led to the realization of
many optical properties in fiber form that were not previously attainable. This chapter …
